I am considering reolacing the failing 14in. tube
in this set with the 17in. MW34-69 c.r.t. I realise
the obvious mechanical changes of course, but a”trt from these could you indicate any other d’rfi,ulties involved in the operation.-K. Fordham
(Fnlbourn. Cambridge). The CRM141 and CRM142 have smaller neck
diameters than the MW43-69 and the scanning coils would therefore be a tight fit. The correct 17in.
tube to be used is the Mazda CRM171.
